How to propagate蟹脚兰 (Crane Flower)
As an epiphytic plant of the cactus family, the蟹脚兰 is deeply loved for its unique crab claw shape and the characteristic of blooming in winter and spring. Cuttage is the most commonly used method for propagating蟹脚兰, and mastering the correct operation skills can increase the survival rate to over 90%. This article illustrates the complete process from stem treatment to root care through 8 key steps.
Four essential elements for successful cuttage of蟹脚兰
Best timing for cuttage
Spring and autumn are the golden periods for cuttage: In November, when the temperature is between 15-20°C, the cambium layer is active and wounds heal quickly; in spring, after flowering, the plant enters the vegetative growth stage, and the mother plant recovers faster when cuttings are taken. It is necessary to avoid the high temperatures of summer (>30°C) and the low temperatures of winter (<10°C).
Standard process for stem treatment
Select 3-7 sections of two-year-old robust leaf-like stems, disinfect the scissors with an alcohol swab, and cut diagonally. Apply charcoal powder to the cut surface to prevent bacterial infection, and place it in a cool and well-ventilated area for 3 days until the cut forms callus tissue, a process that can effectively prevent black rot disease.
Smart substrate mixing solution
It is recommended to use a mixed substrate of peat soil: perlite: vermiculite in a ratio of 5:3:2, which has both water retention and breathability. Before cuttage, water the substrate thoroughly with a fungicide solution of carbendazim 800 times, maintaining humidity at around 60%. Avoid using uncomposted organic fertilizers, as they can cause root rot.
Three key points for environmental control
① Light: Place in a scattered light environment to avoid direct sunlight burns; ② Humidity: Mist daily to maintain air humidity at 70%, and water when the surface of the potting soil is slightly dry; ③ Temperature: Maintain a constant temperature of 18-25°C, and use a transparent plastic bag to create a mini greenhouse effect.
New roots are generally visible in 15-20 days, and transplantation can be done after the new buds have grown 2 complete stem sections. It is recommended to use ceramic pots for planting, and change to acidic soil rich in humus (pH 5.5-6.5) every spring. The application of phosphorus and potassium fertilizers can promote bud differentiation.
